Production at Corby
underway
Charitable computing
The production line is getting
under way at the Commodore's
new Corby factory, although the
official opening is not until
Autumn when the VIP, yet unan-
nounced cuts the red ribbon.
The factory has already cost
Commodore over £20 million
and covers 200,000 square feet. It
will eventually have the capacity
to produce 3,500 computers a
month, but in the initial stages just
2,000 computers — a combina-
tion of Plus/4, C16 and 64's - will
be manufactured each month.
Commodore hope to have
enough of their new machines to
cater for the anticipated
Christmas demand. A variety of
peripherals and software will
also be made in the factory,
but Commodore's branch in
Braunschweig, West Germany
will still be responsible for the
8000 series and a number of
other products.
Most of the staff have moved up
to Corby from Slough, although
John Baxter, Marketing Director
for Commodore (UK) is expected
to depart in the near future. As
yet, no replacement has been
announced.
There are no plans for the
Slough factory and it will
eventually cease production.
Commodore postpone
show
Commodore's cancellation of the
Leeds Show was due to two
factors according to Aileen
Bradley, Commodore's Retail
Marketing Manager.
She explained that as Com-
modore are moving to their
Corby offices in September "a
great many staff and resources
Marks and
software
Marks and Spencer are venturing
into software and hope to have a
selection of titles on the shelves
before Christmas.
Adrian Shire, senior selector,
told us that they would initially be
stocking a number of game titles
as well as educational and utility
programs for the Spectrum.
If the experiment works well,
titles for the 64 will be added to
the range. Since the project is still
in the early stages, Adrian Shire
felt it would be imprudent to give
us any more details, but watch
this space!

will be tied up during the month"
and so they would be without "a
full complement" of staff to help
with the show.
In addition, Commodore ex-
pect to be extremely busy during
the run up to Christmas with
production of the new 16 and
Plus/4 computers.
15,200 people attended the
Commodore Show held earlier
this year although Commodore
had anticipated that last year's
attendence figures of 40,000
would increase this year.
Record
UK sales
Following news of Commodore's
record worldwide sales, we can
now report that their UK sales
contributed substantially to this
record.
UK sales topped the £100 mil-
lion mark during the last financial
year. Howard Stanworth, General
Manager, comments: "It confirms
that, in revenue terms, we are still
the undisputed leader in the
British home computer market."
A computerised Tombola charity
stall has raised £2000 for the Sick
Childrens Trust 'Home from
Home' appeal.
The idea was conceived by Bob
Barton of Romik Software and
Fiona Anderson, Organiser of the
Commodore Show. The stalls
were held at the Commodore
Computer Show and Computer
Fair.
Exhibitors donated blank cas-
settes, games, books, joysticks,
computers — Commodore Com-
puting International donating a
large number of back issues.

FAST fight
for change
FAST, the Federation Against
Software Theft, has gained the
support of the majority of leading
companies and trade associ-
ations.
Launched earlier this year to
fight software piracy, FAST plan to
achieve legislative changes in the
Copyright Act so that more
criminal remedies are available
for software copiers. In effect, the
changes should add more penal-
ties to those existing for the
manufacture, importation and
distribution of pirate copies. FAST
also plan to increase awareness
of the legal protection already
available under existing law.
The Rt Hon Kenneth Baker, MP,
Minister of State, Department of
Trade and Industry warmly
welcomes FASTs' ideas. He says:
'The software industry is a very
important and quickly growing
sector of the British economy. It is
already a major contributor to
national wealth and employment
in this country and it is essential
that it should be in a position to
protect itself against unlawful
copying". He also says that he
"would like to assure FAST of my
support and encouragement for
their valuable efforts in this area."

helped to attract large crowds
and the money raised will go
towards providing accommod-
ation for parents of seriously ill
children attending the Hospital
for Sick Children at Great
Ormond Street and St
Bartholomew's.
And in a similar vein — strenuous
endurance feats such as Banana
gobbling, Welly throwing and Egg
hurling events featured signifi-
cantly in the Wickes Associates
alternative to the Los Angeles
Games — the Waiward Olympics.
The event, held recently at the
Thames Ditton Sports and Squash
Club, attracted more than 85
clients and journalists, raising
more than £400 for the
Dedisham School for Autistic
Children.
Commodore's
bronze
Commodore sold enough
machines last year (1983) to
achieve a third position in the
1984 BIS-Pedder Annual Census
of Information Processing.
Their market share rose from
3.6% in 1982 to 6.3% in 1983, a
total rise of about £80 million.

Dealer of
the year
The Commodore dealership of
the year has been won by the
Birmingham-based Camden
Computers.
To qualify for this title, Camden
Computers sold more than
£800,000 worth of Commodore
equipment before the year
ending June 1984.
Camden Computers was
formed in 1971 and has been a
Commodore Approved Dealer

Louis
. ijv H Ri' eV Hugh Riley, the overall winner
, = 12°) of the £5,000 endowment in the 18+
(tv1ed' tatl ° Dynamic category, has only had his computer since
Christmas. And his winning entries Louis (Meditation Failure
= 126) and Obsessiveness were his first attempt at this kind of
programming. A simple, yet extremely effective entry, Louis shows
the face of a baby, his eyes following the path of a fly. Don't blink or
you'll miss its grand finale - as the fly lands on Louis' nose, out flicks
a long red tongue and gobbles it up! Slightly reminiscent of the
mutant baby in the wonderfully awful TV epic V.
Hugh Riley explains where his ideas came from. "The idea called
for a face. If s actually the face of my son taken from a photograph. I
suppose the idea for the fly had just been buzzing around my head."
GROAN!
"The programs are complex within their simple limits," continues
Hugh. "The Commodore allows you to move sprites, but you still
have to define the blocks of pixels to be moved."
I didn't have the opportunity to see Hugh's other entry,
Obsessiveness, which involves the repitition of the word
Obsessiveness.
"The screen was 40 characters wide," commments Hugh.
"Therefore I needed a word 13 characters long - Obsessiveness
was the obvious choice."
Producing a work of art using a computer
may still seem futuristic to some, but
watercolour and oil painting were declared
equally innovative in their time.
Commodore's International Art Challenge
has brought to the public's attention the
possibility of micro technology in image
making.
The aim of the challenge was to open up an
unexplored area to home computer owners
and to demonstrate that new technology can
be visually and artistically exciting as well as
indispensable for use in education and solving
practical problems.
Incentives to enter included a £5,000
endowment towards enabling the overall
winner to study computer art at the estab-
lishment of his, or her, choice anywhere in the
world in addition to thousands of pounds
worth of Commodore equipment to be won.
The first art challenge of its kind, it stimulated
a favourable response. Two hundred entries
were received - perhaps not as many as
expected, but the timing of the challenge
meant that many potential competitors were
under pressure from school exams.
Entries were judged for technical as well as
artistic excellence by a panel of judges which
included Professor Brian Allison, world
president of the International Society for
The Park by R Hadland
Nine-year-old Richard Hadland produced a striking mosaic-
type picture of a park which earned him first prize in the
Under 12 Still category.
Richard uses a computer at school, but programmed his
entry on his Dad's VIC 20, which he has been
experimenting with on and off for about a year.
Art is a subject Richard enjoys and he has tried his hand
at computer graphics before. He says: "My Dad told me
about the competition. I thought that I could make a tree
and I decided to make it a park with a friend and a slide."
It took Richard just three hours to produce his entry, with
perhaps just the tiniest bit of help from his Dad with the
actual program. He's planning to invest in a 64 with part of
his £1,500 prize money - I wonder if Dad will be allowed
to use it?

ational Computer Art Challenge. In addition to
to some of the entrants and Judges
Education through Art, Commodore's market-
ing manager John Baxter, Paul Brown, editor of
Page — the journal of the Computer Arts
Society, and artist Tony Hart.
The winnng entries were on public display at
London's Hamilton Gallery from September
3-5. Unfortunately we didn't have enough
notice to announce this earlier.
I didn't envy the judges the task they per-
formed in singling out the winning entries. At
our photographic session I saw only a small
sample of the entries and the standard was
impressive. (I also don't envy the considerable
hours put in by the judges waiting for each
individual entry to be loaded — not that
Commmodore ever encounter problems with
their disk drives and cassette units. Cough!
cough!)
My personal favourite has to be Mr
Freakenstein which was voted the overall inter-
national winner. (I must have good taste after
all!) A Swedish entry by 14-year-old J Wester, it
shows Freakenstein at his VIC 20 keyboard,
fingers moving up and down while the eyes
blink and an evil sneer appears on his face.
All of us here at CCI would like to add our
congratulations to the winners. If you missed
your chance to prove your artistic talents this
time, don't worry. Commodore are planning to
repeat the challenge next year.
Bull Toad (from Artist 64 Gallery) by LK Gibson
Talking to Swedish 14-year old J Wester
posed rather a problem as his command of English
was not sufficient to discuss his winning entry, Mr
Freakenstein. However, it far surpassed my knowledge of the
Swedish language! Due to this language problem I will also have to refer
to him as Mr Wester as when I enquired about his first name, he replied:
"I don't spell in English". Anyway, it is pronounced something like'Yohanik'.
His entry, Mr Freakenstein, won him first prize in the 12-17 Dynamic
category and gained him the title of International winner. Mr Freakenstein
was actually the result of a misinterpretation. Mr Wester says: "My first
thought was to do Einstein.
My father thought I meant
Frankenstein, so I decided
to work on that idea. "It
wasn't very easy," he
continues, "But it also wasn't
hard. It took two days to
develop the idea and then I
wrote a program so that I
could generate my
characters."

John Baxter, marketing manager of Commodore UK, feels that the
Commodore International Computer Art Challenge has been a huge
success. He comments: "The standard of entries was extremely high,
especially considering that it was the first ever competition of this Kind for
home computer users, and that no extra add-on software was permitted in
creating the graphics."
As part of the judging panel for his knowledge of the technical expertise
of each entry, Baxter was involved in the difficult task of selecting the final
winners. "It was a task which stimulated much discussion amongst the
judges," says Baxter. Despite the number of outstanding entries, the judges
were unanimous in their decisions.
Baxter confirms: "Louis (Meditation Failure = 126) was immediately
obvious as our overall winner. It stood out head and shoulders above the
rest particularly for its high degree of originality and creativity. It also
exemplified the excellent standards of technical expertise in the blinking
eye which, although appearing to be a simple movement, does in fact
require great skill to achieve.

Catch A " ir "Mr Freakenstein was another
clear winner," he continues. "It
demonstrated probably the highest level of
excellent and accurate imagery I have seen
performed on a VIC 20 with no memory
expansion at all."
Baxter concludes: "The Commodore
International Art Challenge has shown that
Commodore's home computers have
capabilities in fields which are only now
beginning to be explored - even the
youngest of children are capable of using
their computers to create what we believe
will be the art of the future."
Professor Brian Allison, world president of the
International Society for Education through Art,
was concerned mainly with the educational
value of the competition.
He says: "I was encouraged by the number of
demonstrations of computer usage in art and
design activity in schools. It showed the
potential of young people to use the computer
in an aesthetic way and adds to the range of
techniques available to artists for expressive
purposes."
Allison confirmed that the standard of entries
was high and expressed his delight in the fact
that entries were received from women.
"I was particularly taken by an entry from a
10-year-old girl," comments Allison, referring to
The Knight and the Sprite by Joanne Delaney.
"It was a lovely poem and the image making
was good too." According to Allison, school
computers tend to be hogged by the boys and
he feels that these results will encourage more
participation from girls.
In any future competitions of this nature,
Allison would like to see a category for school
entries. He says: "Given the time of the year
when the challenge was set up, 15-18 year olds
were all involved in exams. Many were away
from school, so a computer was required at
home.
"The timing didn't allow teachers to become
involved. With a category for school entries, an
educational venture could be fitted into the
regular school program."

First, a question.
Who do you think are the
world's most avid consumers of
microcomputers?
The ingenious Japanese?
The fashionable French?
The acquisitive Americans?
Believe it or not, it's we
British who own more micros
per person than any other nation
on earth.
Yet, despite its amazing
impact, the microcomputer has
only just begun to scratch at the
surface of our lives. Without
doubt, the best is yet to come.
Use and Abuse.
In several recent surveys,
some astonishing facts about
micro use and abuse were
revealed.
It was discovered that the
micro is hopelessly under-
utilised. If you're already a micro
owner, your own experience may
well confirm this unhappy state
of affairs.
Brainpower. A source
of knowledge.
For thousands of years,
the key to self improvement has
been in the hands of the written
word. Now, thanks to
the Brainpower range, it's very
much in the hands of the micro
As the Brainpower
range demonstrates, this does not
require prior knowledge of micros, or
how they work.
The Brainpower concept has
been devised as integrated applications
and educational software. And its aim
^."•^yy^r '.*'^,^-'>

Each Brainpower title provides a unique three part package: an applications
program, a teaching program and an illustrated manual and interactive
tutorial - integrated applications and educational software.
Now you and j

is to stretch both your mind and your
imagination.
It offers a unique way to realise
your own full potential and that of your
micro. In a way you could never hope to
achieve from the printed word alone.
In this respect, the Brainpower
range stands on its own.
A unique concept.
All the Brainpower titles share
one thing in common, apart from their
stimulating subject matter, that makes
them unique.
You will find each title comprises
three distinctive elements: A teaching
program that helps you to get to grips
STAR WATCHER
The secrets of the heavens are yours. Isolate all the
constellations as well as main stars for easy
identification. Even turn stars and constellations on
and off at will. Screen by screen, you will see exactly
how the 1,500 brightest stars move through time and
space. And all from any point on the Earth's surface at
any time of the year.
Star Watcher is without doubt the definitive home
observatory.
DECISION MAKER
Should you buy a new
house? Change jobs?
Have children? Start your
own business? Such
decisions should not be
taken lightly. Armed
with Decision Maker, you
can be quite sure of
examining every avenue,
and arriving at a rational,
structured answer.
If you value the way
you run your life, you
need Decision Maker.
NUMBERS AT WORK
Tackle all the number problems you're likely to face in
daily and business life. From straightforward
multiplication and division of fractions, through
decimals, percentages, ratios, mark-ups and margins
to compound interest, depreciation, VAT and PAYE.
Numbers at Work gives you a distinct edge, since
you will be able to both understand and manipulate
numbers at will.
PROJECT PLANNER
Project Planner teaches you how to divide even
the most complex project down into meaningful
components. Learn how to determine the length
and importance of every single task, and those
elements critical to the fulfilment of your plan. Even
anticipate problems you hadn't envisaged.
You have the measure of any situation because
you have the fullest possible grasp of all the factors
which affect it.
rour micro can
;st in each other:
FORECASTER
Forecaster takes the guesswork out of forecasting, by
accepting that tomorrow's events will be best
predicted on the basis of today's facts. Armed with
Forecaster, sales targets and growth trends, even
sporting events and election results can be
accurately and very quickly predicted.
Invaluable to you in both your private and
business life.
with the subject at your own pace. An
applications program to put what you
learn into action. And finally, with each
package, you get an expertly written
book and interactive tutorial.
ENTREPRENEUR
Entrepreneur teaches you all the steps required to plan and start
your own business. It will forecast your first 18 months' cash flows,
generate your Profit and Loss Account and Balance Sheet. Help
you in discussions with your bank manager and partners. Explain
the notions of assets, liabilities, overheads, working capital, cash
flow and break even point.

GRAPHICS
Graphic generation
Confused by the multitudes of graphics aids available?
Sally Wood investigates this ever increasing sector of the market
Computer graphics have changed theface
of the film industry. Special effects
created with the aid of computers have made
possible cinematic extravaganzas such as Star
Wars, Tron and Return of the Jedi all multi
million blockbusters.
Imaging techniques have also made signifi-
cant changes to scientific research
procedures. Computer graphics can be used
in the design of new drugs, in genetic
engineering, for improving and interpreting
images sent back by space satellites and even
for the examination of bone structures before
surgery.
The potential uses for computer graphics
must be enormous and no doubt in the next
few years they will increasingly become part
of our everyday lives. However, science and
film entertainment apart, what about down
to earth personal computer use of graphics?
The average computer programmer is not
going to start designing graphic programs to
plot the path of particles in nuclear energy
research, nor is he going to start creating the
special effects for the latest Spielberg film.
What he or she will be doing, is to utilise the
myriads of proliferating graphic packages for
applications such as business, education,
remedial teaching, in personal programs and
even for the aesthetic pleasure of designing
amazingly clever pictures for contests like the
Commodore International Art Challenge, the
winning entries of which are featured in this
issue.
Lines, circles, shapes, close ups, plotting
lines, up to fifty colours (achieved by com-
bining Commodores 16 colours), squares,
filling in of shapes, different textures can all be
used in creating graphic images on the
television or monitor screens either using the
preprogrammed graphics programs or
programming your own using the utilities
which add extra graphics commands to
BASIC.
Most of the packages are for the 64 and this
bias is due to the incredible graphics potential
of that computer. It has five graphic modes
altogether. Two of these, the high resolution
bit mapped graphics and multicolour text
modes, can be mixed with text.
Normal text, extended background colour
text and multicolour bit mapped graphics
mode are the other three modes and using
these, foreground and backgrounds can be
defined on screen. There are also four layers
of animation and eight sprite layers to play
around with!
No wonder there are such brilliant graphics
in 64 games like Alice in Videoland and Aztec
Challenge by Audiogenic or Loco by AHigata.
Even the VIC 20 has a relatively good graphics
capacity and games like Pharoahs Curse by
Hesware prove it.
We have put together a list of a selection of
available graphics packages which will give
you a good idea of what is available.
It is not possible to categorise the packages
as each one concentrates on different aspects
of computer graphics. Some require periph-
erals such as graphics boards, light pens and
joysticks.
There is much room for development and
improvements in the field of computer
graphics and so it will undoubtably become
even more exciting than it is already. We
hope that your creative interest has been
stimulated — creating and designing graphical
imaes on a computer will, undoubtably,
produce pleasing results.

A spritely interlude
It's welcome back to Pete Gerrard who has taken time off
from writing his successful computer books and games to
provide us with this insight into how collision detection
with fellow sprites and data works
Sprites are an often used feature of the
Commodore 64, and are one of the most
powerful of it's graphical capabilities. Yet
each month the computer magazines see a
host of letters concerning these little beasts,
and in particular everyone wants to know,
and few seem to understand, how collision
detection with both fellow sprites and data
works.
For the purposes of this article, we might as
well get a sprite on the screen, so the follow-
ing short program will accomplish this for us.

Sprite Inverter
Before getting into the nitty gritty, let's see
how this program works. It takes a sprite (any
sprite) and inverts it's image on the screen. In
other words, instead of having two lots of
data for two different sprites, and invariably
getting it slightly wrong, this program will turn
one sprite on its head, and reverse it back
again, at the touch of a key.
Explanation
Line 5 : Just set up a couple of arrays.
Line 10 : We'll have a black border and a black
background, and just print up a simple mes-
sage. You may care to clear the screen at this
point, just to make things a bit more legible.
Then, go to the subroutine starting at line
30000 to set up the sprite, and then go to the
subroutine starting at line 996 to invert the
sprite.
Line 15 : Set the variable V, and magnify the
sprite in the X and Y directions.
Line 20 : Turn the sprite on, and give it an X co-
ordinate of 160 and a Y co-ordinate of 120,
which puts it in a fairly central spot on the
screen.
Line 22 : Just a set of instructions.
Line 24 : Get a key press, and if that key is the
'U' one then go to line 34.
Line 25 : If the key isn't the 'D' one then return
to line 24 and wait until either 'U' or 'D' is
pressed.
Line 32 : We're inverting the sprite, so put all
the data in the SD array into the 13th area of
sprite data.
Line 33 : Bit obvious, this one.
Line 34 : We're turning the sprite the right way
up again, so put all the data in the SD array
into the 13th area of sprite data.
Line 996 : Start of two loops that performs the
inversion.
Line 997 : Going in steps of three, take the
bottom rowoftheoriginal sprite, and put it in
the top row of the inverted one. In other
words, we're simply swopping data around in
steps of three.
Line 998 : Carry on the loops.
Line 999 : Do the last three elements of the
array the long way, and return from this
routine.
Line 30000 : Read in the sprite data for the
normal sprite, put it in the 1 3th block of sprite
memory, and also put it into the array SP.
Then, inform the computer where you've put
the data, and turn it into a yellow sprite
before returning from this routine.
The program works, is it's chief feature, and it
does get a sprite on the screen.
Collision Detection
Provided that you've cleared the screen,
that last program should have a sprite sitting
serenely in the middle of it, touching neither
sprite nor background data.
If we were now to PEEK registers 53278 and
53279 we would get a value of zero in each of
them, for it is these two registers which deter-
mine which sprite has collided with what.
Location 53278 works in the following way:
Sprite Number 7 6 5 4 3 2 10
Value 128 64 32 16 8 4 2 1
If the location contains a zero, then there
are no sprite to sprite collisions taking place. If
the location contains a one, then sprite zero is
involved, a two indicates a sprite one colli-
sion, and so on, until a value of 128 would
indicate that sprite seven is involved. Of
course, since this location detects sprite to
sprite collisions, it would never contain a
simple value as outlined above, since there
must be at least two sprites together to
register a collision in the first place.
So, if the value found from PEEKing that
location was, say, 17, it would mean that
sprites four and zero have collided. A value of
36 would indicate that sprites five and two
have collided.
Multiple sprite collisions are also possible,
so if the value of PEEK(53278) was found to be
41, then sprites five, three and zero are all
involved. If the value is 255, then every sprite
in the world is involved, and there'll be a
grubby mass of sprites somewhere on the
screen.
Or maybe not, since sprites can collide off
screen as well, so watch out.
To illustrate this in action, add the following
lines to your program:
16 POKE2041,13:POKE53288,5
23 PRINT"[HOME,8SP,HOME]"PEEK
(53278):PEEK(53279)
and alter the following lines as well:
15 V=53248:POKEV+23,3:POKEV+29,3
20 POKEV+21,3:POKEV+1,120:POKEV,160:
POKEV+3,110:POKEV+2,150
Running the program with these alterations
will put a second sprite on the screen, touch-
ing the first one, and the value in location
53278 is now displayed in the top left hand
corner of the screen. The value next to it is
that for location 53279, which presently
contains zero as there is no background data
on the screen.
Collision: What collision?
So handling sprite to sprite collisions is quite
straightforward. But what about sprite to
data? Here we are not concerned with the
value to be found in location 53279 other
than being satisfied that it does not contain
zero. As long as it holds some other value,
then that serves to tell us that the sprite has
collided with something.
Say we want to check for sprite zero. We
know that the X and Y co-ordinates for sprite
zero are held in locations 53248 and 53249
respectively. As soon as a sprite to data
collision is detected, a PEEK of these locations
will give us the X and Y co-ordinates for the
sprite.
Say we get the values of one hundred and
fifty for X and one hundred and twenty five for
Y at the moment of collision. Divide X by
eight and Y by eight to give us the new values
of eighteen and fifteen respectively, after
taking the INTeger part of the answer only.
Multiplying the Y value by forty gives us a
value of six hundred, and adding our X value
of eighteen to this gives us a total of six
hundred and eighteen.
Add this to the screen start value, which is
usually one thousand and twenty four, and
we arrive at a final total of 1 642. Now, at least,
if we type PEEK(1642) we can find out what
was on the screen when the sprite hit it.
A complicated process maybe, but it works,
and the following program shows this in
action.

THE COMPANION TO THE
COMMODORE 64
Any book claiming to be a companion to the
Commodore 64 Reference Guide, would
have to be of outstanding quality to justify
that claim. This book, as it happens, is.
Whereas the Commodore 64 Reference
Guide concentrates on the more technical
aspects of the 64, Keith Bowden has tried to
emphasise the creative uses of the 64's
excellent graphical and sound capabilities.
The book is a mine of information. Chapters
are split up to deal with the 64's machina-
tions: its 6510 memory organisations, sound
and graphics capabilities, character and sprite
animations and the relevance of raster inter-
rupts.
If the Reference Guide has already gone
into detail about certain aspects of the 64,
Bowden does not waste his time covering the
same ground. For instance in the chapter
devoted to animation, he does not go into
detail about sprites as they are already
chronicled in the Reference Guide.
Bowden has taken care to include practical
programming aids such as machine code
interrupt routines which can be used to drive
animated displays or for generating music
and music interpreters to create background
music (Magic Roundabout in this instance)
while programming. BASIC version of
routines are also included.
In addition three main BASIC programs are
listed to reinforce the explanations of the SID
and VIC II chips and their significance to the
64's sound and graphics facilities. A syn-
thesiser program, enables the programmer
to create sounds with the SID chip and the
other two graphics programs enable bit-
mapped pictures in both high resolution and
multi colour to be designed.
The author has also reviewed some utilities,
games and books that he considers helpful
and has listed a number of 64 locations.
Bowden's obvious enthusiasm for the 64's
potential overwhelms the reader. However
the reams of information stuffed into the
pages does sometimes cause the mind to
wander. Fortunately it soon returns when yet
another programming gem is discovered.
There is no doubt that any 64 owner keen
to start inventing games or other programs
on the 64 will find this book, together with the
Commodore 64 Reference Guide, an invalu-
able aid. Well worth £5.95.

Personal Computer News, Cavaye Place,
London SW10.
THE ADVANCED 64 HANDBOOK
This book could be used as a small reference
volume and dipped into when information
on various aspects of the 64 are needed.
Information has been consigned to the
numerous chapters in a methodical and un-
complicated way. If the reader is stuck on a
particular aspect of the 64, for instance
display interrups, the MPS 801 dot matrix
printer, advanced disk operation with the
1541 disk drive or even finding out how to
increase the 'user friendliness' of personal
programs, he or she will find locating the
relevant section easy. Another bonus is that
the text is not filled with unnecessary waffle.
Peter Lupton and Frazer Robinson intend
the handbook to be a companion guide to
the "Commodore 64 Handbook", published
by the same company, and assume that the
reader will be familiar with BASIC. Their aim is
to provide the reader with the opportunity to
find out even more about the 64.
A large section of the book is devoted to
machine code. It is a difficult language to
understand, but since it is the 64's own
language it is important to make the effort.
The 6510 Microprocessor's architecture, the
instruction set used and its various oper-
ational abilities are all explained.
Throughout the book, diagrams, program
listings and programming sequences are used
to reinforce and illustrate the text.
Other chapters in the book cover the
various graphic modes of the 64 - standard
and multi coloured bit mapped graphics, the
VIC II chip and display interrupts plus the SID
chip and methods of playing tunes with the
synthesiser.
The authors have also included a number of
appendices which the programmer may find
invaluable, for instance error messages and
their explanations, a summary of DOS com-
mands, BASIC abbreviations, Kernal routines
graphics loader programs and both SID and
VIC II registers.
The authors have eliminated any unneces-
sary padding and although nothing is covered
in extensive detail, no-one will mind that the
book is not a totally authorative text, because
it does convey, in a clear and concise fashion,
what it is he or she wants to know. Detailed
information can always be located some-
where else. The books usefulness justifies the
price of £6.95.

THE COMMODORE 64 PUZZLE BOOK
We are told in the introduction that life is one
long problem solving experience, a condition
analagous to programming the computer.
Both require solutions, but these are
invariably arrived at by different means.
Brian Boyde Shaw assumes the reader has
at least a minimum working knowledge of
BASIC and poses over forty programming
problems for the reader to solve with his 64.
They are not, as the title suggests, puzzles in
the conventional sense - crosswords or
general knowledge quizzes, but problems re-
quiring solutions reached by using the
computer.
The problems are divided into six sets and
Boyde Shaw has graded them in order of
complexity. The novice programmer can
begin by learning relatively simple proced-
ures with posers such as "Write a program to
print your name on a completely clear
screen" and then goes onto harder problems
dealing with topics such as screen printing,
string and other logical functions, basic
games routines and the relationship of letters
to numbers, using methods lamed in earlier
problems.
The final chapter deals with a mixture of
topics including conversions and music, with
one of the last problems asking the program-
mer to use the television screen as a digital
clock displaying hours, minutes and seconds.
Boyde Shaw provides all the possible
answers to the problems in the book and
does his best to explain how he has arrived at
them using both text and programs. The main
BASIC language commands are listed in the
first chapter, but any other commands that
are necessary in problems are listed at the
front of the relevant chapter. An aid
reminiscent of early learning reading books,
where all new words are listed!
Boyde Shaw emphasises that the book is
not designed to teach anyone computer pro-
gramming, but to develop the ability to think
logically and solve problems.
Written in entertaining and uncomplicated
prose, this book would be worth the £6.95
for anyone who enjoys solving problems.

26 Commodore Computing September 1984
Dear Sir
I have been purchasing Commodore
Computing International for a number of
months now and find the contents very good.
Being new to the use of computers, I still rely
on magazines like yours to inform me on the
latest products and news.
However some of your programs seem to
have a number of printer errors and the latest
appeared in "Maze" from the May issue. I
found that there was a bad subscript in line
510. Could you please help, these minor
problems spoil for me what is otherwise a
good magazine. Mr T Fromson
Tyne and Wear
We are pleased that you enjoy our magazine,
but feel that your comments on our programs
are unfair. We thoroughly check all programs
before they are printed and in our experience
it is usually the programmer who makes the
error!
It sounds as if you have missed out either
the 'W or '%' from lines 510 or 340. The
printed program is correct and so we advise
you to check these lines again.
Dear Sir
I am slowly going round the twist!
I have a VIC 20 with a Stack RS232C inter-
face attached to the back. I also have a
Brother CE60 Electronic daisy wheel printer
which connects to the VIC 20 via a Brother
cable and its interface. The printer accepts
both RS232C and Centronics parallel, but the
whole shooting match fails to come alive!
The Stack interface has a 25 pin male plug
on the back of it and so, unfortunately does
the Brother cable. However by VERY careful
soldering I have paralleled off the pins so that
the cable will accept a 25 pin socket. It still
fails to operate, I know not why.
Can you please throw some light on the
subject, I should hate to think that
Commodore have led me up the garden
path. ASA Clack
Cirencester
Clos
It is very difficult to advise you on your
predicament without seeing the printer
manuals first. Your best course of action
would be to contact the company who made
the printer.
Your problem highlights the need for all
Commodore computer owners to look at the
printer market carefully before investing.
Commodore, in their wisdom have included
their own interfaces in all the computers, so
not all printers will operate satisfactorily with
them — as vou seem to have found out.

Dear Sir
I am having trouble with the Breakout
program in the April issue, No 11 Vol 2.
Everytime I enter the program, I get a
constant "Out of Data" error shown with
respect to line 1190 (ReadA:Poke1,A:Next:
Coto1280). Is this line correct?
I also noticed that in the Cursor Character
Box, page 49, if I pressed the control key and
key 3 I should print . However when I do
press these keys, I get . Can you enlighten
me?
Mr J Moore
Hartlepool
Cleveland
The Breakout program is correct. It sounds as
if you need to check your data again.
The characters in the Cursor Character box
are shown as they appear on our
Commodore printer and on our listings. We
don't print the characters as they appear on
the 64's screen as we think it will be easier for
programmers to type in programs from the
published listings.
Dear Sir
In the May issue of Commodore Computing
International, you have a software review
entitled "Elementary Watson". Unfortunately
my husband and I have had trouble obtaining
a copy of Dr Watson's Beginners Basic Course
plus Honey Aid, with book and tape for the
64.
We are both pleased with your magazine. It
is very explicit and unlike others, the print is
clear and understandable.

Dear Sir
I recently saw a program featuring a develop-
ment rack. Printed circuit boards with extra
chips and Eproms slot into the rack and it
connects them to a computer system. The
rack can be used in the development stages
of a program and what I would like to know is
whether there is a rack available for the 64.
Antonio Windas
Hull
The simple answer is that there isn't! The 64
has a large enough memory for most pro-
gramming purposes and so there isn't a
market for memory expanders.
Dear Sir
Firstly, thank you for providing a publication
which caters for both the novice and the pro-
ficient in Commodore computing.
Secondly, I wonder if you could furnish me
with some advice.
I would like to ieam more about Machine
Code programming on the 64. I have dab-
bled with machine code on a VIC 20,
laboriously POKEing the code into memory,
so I am familiar with mnemonics and source
code.
However when attempting to actually buy
an Assembler, I become baffled by the
advertising claims of the many suppliers.
They all seem to assume that prospective
purchasers are familiar with technical terms
relating to their products. Some boast the
number of "pseudo - ops" and "control
commands" while others inform me I can
manipulate blocks of memory, use labels or
output to screen (which I thought I could do
anyway!).
I assume that the only way to find out what
these mysterious tributes are is to buy an
Assembler and see. But, I am fearful that I may
end up with something which I don't need.
Help me please! I am sure there must be
other people like me who would like to
venture into machine code programming,
but lack sufficient knowledge to assess the
merits of any product offer. What about an
article on Assemblers and their relative
merits?

We have had a few letters requesting inform-
ation on machine code for beginners and will
probably be publishing an article on assemb-
lers and machine code in the near future.
At present we use either the Mikro, a full
6502/6510 Assembler (£57.50) from
Supersoft, a resident system which doesn't
require a disk drive, or the Assembler
Development (£24.95) from Commodore.
This is disk based and can create and call
macro routines.
Commodore also do an Assembler Tutor
(£29.95) which claims to be a teaching aid for
would-be assembly programmers.
Contact: Supersoft, Winchester House,
Canning Road, Wealdstone, Harrow,
Middlesex and Commodore, 675 Ajax
Avenue, Slough, Berks.

MACHINE CODE
Store and retrieve
This useful routine for the 64, when initialised, allows you to
store and retrieve up to four screens. This is done by trapping
the function keys in interrupts and storing or collecting screen
data from an area behind the Basic ROM.
It was written by J S Rafferty.
The screen flicking can be done in direct
mode by pressing one of the function keys or
in a Basic program by the use of a few simple
pokes.
The program has several uses - it can be
used to store four sections of a program
listing so that to make an alteration to a
certain line just press a function key and make
the alteration, or for simple screen animation.
By pressing the function key with the shift
key held down, the screen and colour
memory is copied to an area behind the Basic
ROM or by just pressing the function key, the
screen is retrieved.
The program can be entered using the Basic
loader (first listing) but the source code
(MIKRO assembler) is also included.
To control the changing from a Basic
program is as follows:

HINTS ANDTIPS
Disable shift key
Disable shift pattern
The shift key is the only one disabled to start
but with a single poke, any combination of
shift/CBM/control keys can be disabled by
POKEing to location 728:
More useful hints, starting with a routine which disables
shifted or CBM graphics characters. The routine sits in the
Sprite 11 buffer and when initialised disables the shift key.

Disk secrets
A couple of useful hints about using the
Commodore disk drives. Firstly, thanks to
Duncan Gamble of Romik software for the
ideas.
Selective directories
It is known that when loading a disk direc-
tory you can ask for files that have some sort
of pattern matching eg LOAD"$0:TEST*",8
will load in the directory only listing files that
start with "TEST".
A useful directory command that is not
widely known is the selective file types
command which goes like this:
LOAD"S*=P",8 which will only show PRG
files. The other ones are $*=S (SEQ) $*=R
(REL), andS*=U(USR).

HINTS AND TIPS
Locking Files
On the BBC computer, files can be locked
so that they cannot be scratched or saved
over unless unlocked. On Commodore disk
drives files can be locked to prevent
scratching (you can still save over them and
then relock them).
This is done by setting bit 6 of the file type
byte in the directory entry to a one.
Following is a Basic program that will lock a
disk file. If you require unlocking it, just
change line 840 to 840 V=ASC(FTS)AND1 91 .
When a file has been locked, the directory
will show a ' ' character after the file type as
follows.

Scope for design
Programmer Duncan Gamble casts a critical eye over
Audiogenic's Magpie database and the 1541 Express from
RAM Electronics, while Sally Wood looks at Scope,
the games designer from ISP Marketing
SCOPE
"46 commands at the user's disposal."
Scope is a games designer for the 64,
intended to overcome the problems in-
volved in designing a brilliant and original
game.
All good arcade games need bright attrac-
tive graphics and sprites, exciting sound
effects, fast action and of course a detailed
knowledge of Machine Code. Unfortunately
this is often beyond the average program-
mers ability, thus creating a market for games
designer programs such as Scope.
Scope, marketed and written by ISP, is short
for Simple Compilation of Plain Language and
is actually a compiler rather than a games
designer. ISP have created the new language
so that a programmer can type in instructions
for a game program using simplified com-
mands (much easier than in Machine Code).
When completed, his game will be compiled
into Machine Code and then run by means of
SYS commands. The finished program will
run very quickly because it has been written
in Machine Code.
Unfortunately although the commands
were sometimes similar to Basic, typing in the
lines of a program sometimes became rather
awkward and time consuming - every line
number had to be followed by a REM state-
ment, semi colons and colons which the
following exert from one of their demon-
stration routines illustrates.

10 REM ORQ1 5500,20000:
20 REM LABEL;A:
30 REM DVAR;A.O:
40 REM VAR;X,7:
There are 46 commands at the program-
mers disposal and these are devoted to the
creation of animated graphics, sprites,
sounds, colour and music. Scope can only
successfully be used to create arcade games
because of its emphasis on moving graphics.
It is possible to write an entire program
using Scope, but it does have its limitations.
The new language used to write the programs
seems to have been made so thatit can easily
be compiled and this is probably the reason it
appears to be so primitive compared to Basic.
Despite its limitations, Scope may suit a
programmer familiar with Basic who would
like to have a go at producing some game
sequences.
An added bonus for anyone buying Scope is
free membership of the Scope users club.
Each member receives a special card en-
abling him or her free access to a telephone
'hot line' intended to solve all your
programming problems.

1541 EXPRESS
- "increases data transfer speed,
approximately doubling the transmis-
sion rate."
The 1541 single disk drive is a powerful
intelligent unit. It is hampered by the speed of
the serial bus used to communicate between
the drive and the 64.
Serial transmission is inherently slower than
parallel transmission of data because only
one bit is transmitted at a time as opposed to
one byte in 8-bit parallel transmission.
RAM Electronic's 1541 Express cartridge
increases data transfer speed, approximately
doubling the transmission rate.
In programs which require extensive disk
access, the saving in time can be quite ap-
preciable.
The cartridge also redefines the default
filing device to disk rather than tape.
Shift/Runstop loads and runs the first
program on the disk. Loading the directory
can be abbreviated from 10"S",8 to just
10"S, loading a normal program from
10"filename",8 to just 10"filename.
Without the Express cartridge, typing com-
mands on the keyboard while loading and
saving is very unreliable and best avoided.
With the express cartridge in its fast mode,
the keyboard remains fully active and up to

10 characters can be typed in (the length of
the keyboard queue).
Loading from and saving to disk is also pos-
sible with sprites on the screen.
The cartridge can work in its 'fasf mode or
'slow' mode — slow mode is the normal 1541
speed. While working in fast mode there are
limitations on chaining on the serial bus: no
extra drives or printers can be attached. In
slow mode these limitations are relaxed but
some printer interfaces on the serial bus can
not be used with the cartridge plugged in at
all. The manual mentions the CARD? inter-
face.
Printers connected through the user port
are not subject to any of these limitations,
neither is the RS 232 interface.
In the manual for the Express cartridge a
'Fast cable' is mentioned which overcomes
these restrictions.
The Express cartridge can be switched
between fast and slow modes at any time
except actually during disk-access, control
and f1 or f3 switch to fast and slow mode
respectively. This switching was found to be
very well implemented. Even using various
word- processors and assemblers, which
totally take over the machine, the switching
was still effective.
The cartridge port is used so no other soft-
ware in plug-in cartridge form can be used
concurrently.
Commodore Computing September 1 984 47
Installation of the Express cartridge requires
that the 64 is opened up and two leads from
the cartridge be connected to chips on the
PCB. These are attached to the CHAR'EN pin
of the 6510 and the Address Enable Control
line on U14 - the memory switching chip
which controls ROM banking.
Opening up the 64 can void the warranty
on it, so RAM Electronics suggest contacting a
dealer if in any doubt over installation. This is
worthwhile for anyone who is not certain
over installation, as connection to the wrong
pins could conceivably have very unpleasant
results.
The leads end in small sprung clips, so no
MAGPIE
"Magpie's own language resembles
Pascal and Cobol, but is very much
simpler/'
The Magpie database, from Audiogenic,
comes in the form of a cartridge and a disk
with a well-written manual in a tough ring-
bound cover.
Databases allow the efficient storage sort-
ing and retrieval of information, but every
user's needs are different so the database
must be flexible.
Magpie approaches the problem of flexibil-
ity as a language in which the user designs his
own databases.
On switching on. after queries as to disk
drive and printer type, the user is confronted
by a menu of options. Magpie menus are dis-
played as options in blocks on the screen with
the cursor as a line of the menu in reverse
field.
When an option is selected which points to
another menu, this is displayed overlapping
the first menu. It is possible to retrace one's
steps as there is always part of the previous
menu visible.
Menus are displayed in various colours of
varying legibility - white writing on a
medium grey background required much
tweaking of the colour and contrast controls,
even on a colour monitor, to be read.
In the first menu are options to run pro-
cedures, use Magpie's calculator and create
and use systems stored on disk.
The calculator mode provides a very simple
calculator, 26 variables a-z are displayed and
used in expressions.
Evaluation of expressions is left to right, and
only add, subtract, multiply and divide can be
used.
The manual at this point says that the
system is very forgiving, but I found that any
mistakes or attempts to use functions not
supported resulted in the variable being
calculated set to zero and no error message
being generated. Attempting to find the
value of three raised to the power of four
REVIEWS
soldering is required. Once attached, riding
eight miles with the 64 in a rucksack was not
sufficient to dislodge the leads!
When the 64 powers up with the Express
cartridge inserted, the line 'WITH 1541
EXPRESS' appears in white in addition to the
usual power-up message. It is at this point that
the reason for the two leads becomes obvi-
ous. RAM Electronics have cleverly found a
way of adding in extra ROM without lessen-
ing the available user RAM.
Express uses one of the five buffers in the
disk drive in fast mode, two are used by the
DOS, leaving only two free for files. Because
relative files use two buffers and sequential
gave a result of zero!
Magpie comes with a disk on which are help
screens and an example Magpie application.
The help screens are also found in the
manual. They can be called from disk at any
time without disrupting operation of Magpie.
There are help screens for most Magpie
functions but they are usually rewordings of
sections of the manual, not always containing
the information needed by someone in
trouble.
The language that Magpie uses has two
fundamental units — the form and the logic to
control the forms. Forms are designed on
screen. First headings are set up, then fields
are associated with headings. Forms can be
much larger than the 64 screen, a maximum
size of 80 columns by 76 rows approximates
to a sheet of A4 paper. The screen scrolls left
and right and up and down.
Headings are just typed in at the place on
the form required on screen, using the
normal 64 cursor controls. When headings
have been set up, fields are entered. Up to 26
numeric and 26 alphanumeric fields can be
used on a single form and these can be as
long as will fit on the form.
As many forms as will fit in memory can be
used, with two active at any one time.
Forms are the screen display format of data
entry and display. How they are used is
controlled by the program written in
Magpie's own language. This is a high level
language bearing resemblances to Pascal and
Cobol in its structuring, but very much
simpler.
Magpie builds its main menus from pro-
cedure names. Further menus are built from
sub-procedures called from within the main
procedures. One limitation of these is that
they must be defined before the calling
procedure in the text. Magpie cannot look
ahead for sub-procedures.
The language has commands for assigning
any form in memory to be one of the two
current forms that can be in use, allowing
files one buffer, only one relative file or two
sequential files are available at one time.
Because of this use of an extra disk buffer in
fast mode, some programs using several files
or all three buffers normally available will
only work in slow mode: Lode Runner will
not work in fast mode, but Jumpman and
Infocom adventures will.
Trial and error is the only way of determin-
ing whether a piece of software will work
normally. If you are using primarily one soft-
ware package it is worth checking if Express
works with it before investing in this cartridge.
many forms to be used within an application.
The language has very high level single
commands for inputting to all fields in a form,
setting up files on disk and updating files.
Repeat/until loop structures are also
available, as are powerful disk handling
commands for using several drives and de-
vices.
Most commands when writing a Magpie
program are entered by finding the com-
mand in one of the menus of lists in the
Magpie system. Although Magpie has the
facility to allow entering text normally for a
program, it will not recognise commands
typed in in this way.
Its 'enter text' mode is used only for names,
messages and certain variable instructions.
Passwords can be requested at any time
from the user of an application. A password is
entered when an application is created as an
overall password, different passwords can
then be used to protect sensitive areas of the
application.
Magpie has commands for plotting graphs
- bar graphs can be plotted horizontally or
vertically or points plotted. The graphs are
only low resolution character blocks limiting
point resolution.
In Magpie, forms for graphs are resident in
the system itself so they can be called without
having to be defined by the user.
When hard copy is required the printer
usually prints exactly what is on the form.
Some printers, however, use control codes
for underlined or bold text. These are
entered when creating a form and are not
seen on the screen version.
When using a Centronics printer connected
through the user port I found it possible to
hang Magpie, by switching off the printer,
until it was switched on again and printing
resumed. If no printer was connected then
the only way to regain control was by
switching off then on again. Though Magpie's
manual does give a warning on this, a timeout
or abort printing facility would have been
vastly preferable.

Keep your micro motoring
with a printer buffer
When you've invested some serious money in a
micro system, why keep your system waiting while
you print out your hard copy?
If you think about it, you must spend 1-2 hours
every working day just waiting around - unless
you invest in a printer buffer from Interface
Systems.
Whatever micro you're using, our compact
buffers simply plug into your system. So you can
dump pages of text straight into the buffer, leaving
your system free to carry on working for you -
within seconds.
Every Interface System printer buffer comes
with a full 90 day warranty. Yet they're still better
value, bit for bit, than any other comparable buffer
on the market.
We've made it simpler to get your hands on our
buffer too - and our dealer network is still growing.
Simply phone us direct for your nearest supplier,
and start saving system time (and money) today.

Printer match
Omnitronix have developed two
interfaces which will link the 64
and VIC-20 to both Parallel and
Serial printers and enable them
to print out Commodore and
Control characters.
The Parallel printer interface
converts CBM ASCII to standard
ASCII and two keyboard or soft-
ware selectable printing modes
are available.
In mode one, upper/lower case
characters can be printed as
graphics with control and graphic
characters represented as words
and numbers.
Mode two will print upper/
lower case characters with con-
trol and graphic characters
printed as they are. In both
modes, the entire Commodore
graphics set can be printed.
The Parallel Printer Driver disk
or cassette accompanying the
Interface has to be configured to
the correct printer brand before it
will print graphics.
Similarly the Printer driver for
Serial RS232 printers will enable
Commodore graphics and con-
trol characters to be printed. It
has the same functions as the
Parallel driver.
To print actual graphics, a dot
matrix printer with bit map
graphics capabilities and the right
be
printer configuration wi
necessary.
Both Parallel and Serial inter-
faces cost $39.95 (£27) + S1.60

Dr Roger Summit, President of
Knowledge Index believes that
there is a market in Britain for this
type of service because although
vast amounts of information
exist, "it is very hard to find when
you need it!", the purpose of
Information Index being to make
information easily accessible.
Over 20 databases with 21
million separate items covering
journals, books, software pack-
ages and government reports are
incorporated into the system and
topics covered include medicine,
agriculture, education, business,
computers and electronics.
Dialog claim that the service is
fast, powerful and simple to use
because it uses simple command
processors and doesn't require
programming.
A joining fee of £25 entitles the
user to two hours free use and
thereafter the connect time,
which costs £17 an hour, is the
only expense. An average search
costs from 35p to £2. The service
is only available from 6pm to 5am
on Sunday to Friday and from
2pm to 5am on Saturdays.
To use the service, subscribers
will need a terminal, word pro-
cessor with a communications
option, telecommunications soft-
ware, a modem and an RS232C
interface for the PET, 64 or
VIC-20.

"Commodore 64 Sound and
Graphics" by Peter Falconer,
retailing at £6.95 and published
by Melbourne House, will suit
both the naive and experienced
programmer interested in learn-
ing more about these subjects.
The book starts with explan-
ations of what the 64's Sound and
Graphic capabilities are and then
the design and coding of a game
are introduced with respect to
these two features. Finally
machine code routines such as
scrolling, a Raster interrupt
scheduler and a music routine are
shown.
Melbourne House claim that
the book will help readers
unfamiliar with machine code to
gain some competence in "harn-
essing its power".

APPLICATIONS
64 is good for Guy's
Scientists are reputedly compulsive com-
puter games players and Ian Bradbrook is
no exception. Ian, a Lecturer in Forensic
Serology (blood), works in the Department of
Forensic Medicine at Guy's Hospital. His
experience with computers led him to
believe that a computer would be extremely
useful in storingthe masses of data generated
in his work.
Guy's Forensic Medicine Department is one
of the official Home Office blood testers,
carrying out tests to determine paternity in
law suits. By law, the court must order blood
tests of all parties in affiliation. The court gets
in touch with one of the official testers to
arrange for blood samples to be taken either
at Guy's or at a local GP. Blood samples are
then examined to see if there are any exclu-
sions, ie Mr X could not possibly be the father
of the child.
If there are any exclusions tests are
repeated, preferably with fresh blood.
The results are sent back to the court who
then decide whether to accept the proba-
bility of Mr Y being the father.
Whereas it is possible to determine who
isn't the father, blood tests can only prove
that someone belongs to the corresponding
blood group - along with X per cent of the
population.
Here the computer is invaluable in storing
large amounts of information.
The Department of Forensic Medicine
originally had a Sharp computer for which Ian
wrote his own Basic program. When the 64
was launched Ian converted the program to
run on the 64, a decision he has never had
cause to regret.
Last year Ian attended the International
Commodore Show where Precision Software
launched Superbase, a database which was
ideal for his needs.
Sue Pearce is admitted to
Guy's Hospital, not for major
surgery but to discover how
the 64 is being used to
determine paternity
in law suits!
Mounds of paperwork are generated every
day. A day-book lists types of tests and
people being tested. Information is then
transferred to day-sheets which list names of
people and which tests they are undergoing.
At the end of each week, Ian copies the data
onto Superbase, checking back to the original
notes to ensure that no incorrect data is
entered. This system is not particularly time
saving, but it does save a lot of space. Four or
five floppies are easier to store than a moun-
tain of loose paper.
Ian prints his reports out as forms and they
are then typed onto special Home Office
forms which are acceptable in court.
Another advantage of a computerised
system is that if a solicitor should ring to check
on information, the retrieval of information is
substantially quicker. All data is entered along
with the date making it easily accessible.
Ian has written a simple program to calcu-
late the frequency of any particular blood
group. No longer is it necessary to resort to
logarithm tables to determine how many
people in the population have a certain
blood group. Ian just keys in the blood group
and the 64 comes up with the answer.
Superbase is especially useful in the event
of a case which has finished with no exclusion
and when a second man is cited. Or there are
cases with up to four men involved.
Another example where it helps to collate
information quickly and accurately is when
there is a great deal of money at stake as in
the case of inheritance where illegitimate
children now hold the same rights.
There are around 90,000 illegitimate births
a year in this country - one in every six babies
born is illegitimate. Guy's Hospital handle 500
of these cases, a quarter of all in the country.
Most cases are now settled out of court.
The Department of Forensic Medicine deals
with people from all walks of life. From the
famous pop stars (no names mentioned of
course!) to the poor 16-year-old girls who
discover that they need to know the name of
their child's father before they can claim
supplementary benefit and have to think
back to who they were sleeping with at the
time.
lan's 64 also helps him cope with the
laborious task of form filling and letter writing.
Due to the nature of these Ian prefers to
tackle the task himself rather than handing it
to a secretary. He uses Easy Script for the ease
in which he can edit a letter. It is often the case
that when Ian sees it in writing he gets a dif-
ferent view of the case, sometimes noticing a
fact that may have previously been over-
looked.
This information is then stored on disk
which also saves a lot of office space.
lan's department also helps the Met-
ropolitan Police with murder investigations,
matching blood types and analysing samples.
Again the computer speeds up calculations of
the percentage of the population with the
same blood group.
At present lan's colleagues are still doing
their part of the work manually, but he hopes
to eventually put everything on Superbase
and buy a daisy-wheel printer for letter
quality print outs.
Ian assured us that any data built up over
the years which is subsequently used in calcu-
lations of the frequencies of blood groups in
England is all completely anonymous and
that there is no Big Brother syndrome at Guy's
Hospital!

There's one thing the HR-S won't give you.

Once again Alligata's reputation for fast machine
code action and high resolution graphics has
combined to create a classic battle spectacular.
Guardian. Programming perfection, enthralling, fast screen scrolling action
that will test skill and reflexes to breaking point in a desperate defensive mission
against the invading landers. If successful in capturing humanoids from your
planet surface and returning them to native outer space, the landers
will mutate to take up a direct and deadly pursuit upon your space f
fighter. But things aren't quite that easy - the flying pods, i
swarmers, alien bombers and deadly baiters are just as dangerous. /
We know you don't like to be beaten but we're sure you'll
eventually go under. J

Evil Dead hit
by gremlins
There were red faces all
round at a lavish press re-
ception held at the London
Dungeons to mark the
launch of Palace Software's
much publicised 64-game,
The Evil Dead. The game
wasn't ready.
As programmer Richard
Leinfellner was putting the
finishing touches to the
game , he was unaware of the
fact that his disk drive had
crashed, destroying many
hours of hard work. Could it
be that the ancient spirits of
the undead were unwilling
to be raised again?
Curiouser still, when we
eventually laid our hands on
a copy of the game we en-
countered problems with
our 64 's power supply which
prevented us from playing it !
For those of you still wil-
ling to tackle the Evil Dead,
the 64 version costs £6.99.

Olympic mania
The Olympics have finished,
but the race is on for the best
Olympic-based game and as
they flood into the office the
competition for the golden
game will be fierce.
Daley Thompson's Decath-
lon at £7.90, by Ocean
Software, features the ten
Decathlon events and Daley
himself pronounced the
game "fit".
Activision's version of the
Decathlon costs £9.99 and
includes helpful tips by
David Crane, the famous
athlete.
Micro Olympics from
Database costs £5.95 and
involves the player in the
main eleven field and track
events.
Besides these sporty pro-
grams Storm Software have
brought out two programs
filled with facts and figures
on the Olympics. The first
one details all the medal
winners since the Athens
Olympics in 1896 and the
second enables you to record
all the details of the
medallists in the Los Angeles
Olympics and match them
against winners in the
previous two Olympic
games.
Finally, Olympic Skier
from Mr Chip, at £5.99,
provides the thrills and
spills of the Slalom, Ski-
Jump and Downhill events.

Down in price
Price cuts on many of
Audiogenic's older games
have been announced. Motor
Mania and Renaissance for
the 64 and Bonzo for the VIC
20. have been reduced from
£8.95 to £5.95 while Grand-
master's price has been
halved from £17.95 to £8.95
on cassette and £12.95 on
disk.
Audiogenic also plan to
release two new graphic ad-
venture games for the 64 at
the end of the month. In
Magic Stone, the action takes
place in a haunted mansion
and the idea is to transform a
lump of lead into gold with
the help of the magic stone, a
magic word and a book.
Time Traveller occupies
three time dimensions — the
past , present and future . The
player has to pass into the
past and future via a
spaceship, collect vital in-
formation and finally as-
semble a magic hourglass in
the present.

Space race
Legend have finally an-
nounced the follow-up to
Valhalla — The Great Space
Race, described by Legend as
"a spectacular futuristic
romp".
There are numerous space
games on sale, but this one
incorporates a number of
special features — technical
effects created by Movisoft 2,
3D graphics and facial anim-
ation on characters.
There are two phases in
the game. The pre-race
section sees the player
attempting to amass the best
space equipment and then
participating in the "any-
thing goes" race against
time, natural obstacles and
competitors.
By early October, when the
game is due for release,
Legend will have spent S?A
million on its development.
This is believed to be the
largest amount ever spent on
a single game. The price of
the game has yet to be an-
nounced.

Mr Chip have set a mid-
September launch date for
their latest title, Ad
Infinitum. Available on cas-
sette, it will cost about £7
and includes Turbo loader.
The same resembles Space
Invaders, but incorporates
additional features — 256
alien waves assault the
player and it is possible to
progress through all these
levels recording the number
of lives lost rather than
actually losing them.

A female touch
Continuing our look at programmers, Sue Pearce discovers
(shock, horror!) that female programmers do actually exist!
Darran Eter — Artie Games
//p rogramming is something which I have
I just picked up over the years," says
Darran Eter, who recently joined Artie Games'
in-house team of programmers.
An interest in electronics led quite naturally
to Darran becoming a computer hobbyist.
From his original ZX81 computer, he moved
on to the Dragon 32, then a Spectrum and
Darran is now working on the 64. "If s a great
machine," comments Darran. 'The graphics
are good, but I must admit that the 6502
leaves something to be desired."
Darran has been working on 64 games for
Artie for a few months now, but is keeping
any information about them firmly under
wraps for the time being. All he would reveal
was that they are new arcade games.
Never one to be stuck for new ideas, Darrar.
is fortunate in that ideas just spring to mind in
his everyday activities. "I could be doing
something such as watching the television
when I come up with a new idea," he says.
A self-confessed addict of arcade games,
Darran enjoys playing other peoples games
as long as they are good. And Darran's defini-
tion of a good game: "It has to be original and
exciting to play. Normally I prefer arcade
games, but occasionally I find an adventure
that I enjoy playing."
Working methodically, Darran tends to
write everything down, working through the
sections of a game. "I never go straight to the
keyboard," he says.
In the course of talking to various program-
mers, one fact which is emerging is that many
programmers are gradually settling down to a
relatively normal working hours in compari-
son to the early days when the majority
remained glued to their keyboards for up to
20 hours a day!
Darran usually finds himself working a
9-5pm day, although there are occasions
when it is essential to work longer hours to
complete a project. "I've got a computer at
home as well," says Darran. "But if I do use the
computer at home, I always stop at about
midnight - by that time I'm fed up."
Commercial programming is Darran's next
ambition. He comments: "I would imagine
that it is a lot harder to write a commercial
program than a game. Ifs far more math-
ematical, but I've got that sort of brain."
Jean Frost - Addictive Games
Being a woman programmer in what is still
considered to be a male-dominated market
can have its drawbacks as Jean Frost has
discovered. One of the few female program-
mers employed by a software house, Jean
explains: "It's certainly a conversation stop-
per. People think if s strange and assume that I
must be really clever and therefore not worth
talking to."
Jean also finds it hard to live down the
'super-being" image she has encountered. It is
not uncommon for her to receive phone calls
from people asking if she is really a woman.
"Once somebody rang up and asked for Jean
pronounced as the Frenchman's name,"
recalls Jean.
Apart from those who seem unable to con-
ceive that women are every bit as capable of
programming, Jean finds that ifs an enjoyable
way to make a living.
It all started when Jean became disabled
through arthritis five years ago and was
forced to give up her job as an accounts clerk.
A Government Rehabilitation Centre sugges-
ted computer programming and arranged a
course for Jean.
Following her first computing job writing
commercial software for Kalamazoo, Jean
became self-employed writing computer
books such as her Instant Arcade Games
book published by Pan Books.
"I decided that I didn't like being self-
employed," says Jean. "I saw an advert for a
programmer with Addictive Games and got
the job six months ago."
Jean wrote the 64 conversion for Addictive
Games' Football Manager. "The graphic
capabilities of the 64 enabled me to redesign
all the graphics from scratch," comments
Jean. "It took me five months to write and I'm
now sick of playing it."
Watching other people playing her games is
another matter. "Ifs marvellous to watch
other people enjoying a game that I have
written," says Jean. "I get quite big-headed!"
Most of Jean's ideas for games come when
she is ill, but fortunately she doesn't have to
be bedridden to come up with them. Jean
explains: "When I get stuck in bed my mind
begins to turn in on itself. I have the time to
think through new ideas.
"I never go straight onto the keyboard with
a new game," continues Jean. "I tried it but
found you make a lot of mistakes. Ifs much
better to put It down on paper and think it all
through properly." Jean is currently working
on another book, Artificial Intelligence, which
looks at how to give your computer a person-
ality.
Lefs hope we see more women like Jean
making a name for themselves in the
computer world.
Commodore Computing September 1984
Bill Barna - Ocean Software
When Bill Barna decided to learn about micro
processors it was a choice between a ZX80 or
a bread board and bits of wire! Bill explains:
"My background is in electronics, and when I
wanted to learn about processors the ZX80
was the cheapest way to find out how it
worked rather than making something my-
self. The other advantage being that it
showed what was happening on the screen."
What he learnt fascinated him and Bill soon
moved over from electronics, teaching him-
self how to program. An advertisement led to
Bill joining the Ocean team of programmers.
Originally employed to program on the
Dragon, Bill moved on to program on the 64
when a vacancy arose. "The 64 is a superb
machine," he says. "It's got a lot of nice
features which make it a programmers ma-
chine."
Arcade games stimulate ideas for new
games. Bill says: "We tend to develop ideas. If
we like the story line or particular effects of a
game, we will put that idea to use."
Bill was part of the team of three who put
together new Ocean release, Daley
Thompson's Decathalon. This game features
no less than 10 events. Bill programmed the
running events and hurdles. "Some events
involved similar techniques so it was logical
that one person worked on those events,"
says Bill. "For example, javelin and discus
require the same angles."
Each event is really a game in itself, so a
great deal of planning was essential before
rA^flWW/^#i
the game took shape. "We started with a
basic working model illustrating the structure
of the game which we built up until the final
model," comments Bill. "We had to use a lot
of flow charts because the programs, got
pretty involved. A lot was done on paper but
you always have to go back to the computer
to see if an idea works."
"Decathalon was hard," he continues.
"There isn't enough room in the computer to
feature all the sprite data. To get over this
problem the program is constantly flipping
data in and out, moving 4K chunks about to
where it can be read by the VIC chip."
Richard Leinfellner - Palace
Software
Palace has recently entered the computer
software market with the launch of the game
version of its successful film, Evil Dead.
Richard Leinfellner is the man who program-
med the 64-version of Evil Dead.
"When we watched the film we saw im-
mediate potential in the characters and
events for a computer game," says Richard.
"We are keeping to the same storyline, but
obviously not to every scene in the film."
Richard's connection with Palace began
when he started working at the Video Palace
on Saturdays while studying for a degree in
Physics and Electronics. He then worked
there full-time as a sales assistant before the
formation of Palace Software which he joined
as a programmer.
Professionally, Richard has been involved in
computers for a year, but it all began as a
hobby when he was 14. "I built a kit computer
— the Microtown 65, which I learnt 6502 code
on," he says.
The next step was a BBC model which,
Richard says, he never liked. He was then
introduced to the 64 'by force'! Richard
recalls: "It was becoming the best-selling
machine, but I hated it at first. However once I
started getting into Hex and the structure I
started liking it. Now I think it's the best
around."
Evil Dead is the first commercial game
Richard has written, although he used to
program for his own pleasure.
"I'm one of the messiest people I know,"
confides Richard. "I have bits of paper scat-
tered all over the office with Sprite routines
and things on. At certain points of a game I
will scribble things down on flow charts. For
example, with Evil Dead there are a lot of
intelligent routines which I put down on flow
charts - characters in the game that try to find
you."
Richard has his days mapped out. Mornings
are set aside for covering new grounds and
afternoons for sorting out any bugs or prob-
lems. "By about 5pm my brain switches off,"
says Richard, who usually sticks to a 9-5pm
working day apart from when the pressure is
on to get a project finished.
He continues: "I find that when I go home
it's better to switch off completely. I might
play a flight simulator game or watch video.
By the time I get back to work the next day I
can start with a completely fresh mind."

TALES OF THE ARABIAN NIGHTS
Sultan Saladin believed all women to be faith-
less and after he'd spent one night with a wife
he had her put to death (charming)!
The beautiful Princess Anitra is next on the
list and Prince Imrahil sets out to save her.
His quest begins on board a ship where he
has to collect all the jugs spelling ARABIAN
whilst avoiding octopi, cannon balls and
Rocs. Next he negotiates a crocodile infested
river and has to duck the rocks thrown by
hostile nomads. Once in the underground
cavern, mad genies make life very difficult,
but with your brilliant arcade skills, Imrahil
will have no trouble. His final act must be to
grab Anitra and sail away on a magic carpet.
Tales of the Arabian Nights is challenging
entertainment and uses the 64's graphics and
sound capabilities well. The program also
includes a voice synthesiser which introduces
you to the game!

BURNIN' RUBBER
Fast, exciting and marvellous fun. Burnin'
Rubber is compulsive playing and was popu-
lar in the games competition we held at the
Commodore Show.
You are in control of a jumping pink racing
car and command a bird's-eye view of the
'Four Seasons Death race'. The idea is to score
lots of points by knocking fellow competitors
into the side, landing on them and of course
completing each of the 32 rounds in seasonal
order -Spring, Summer, Autumn and Winter.
Fellow demon drivers are also out to win, so
the indestructible pink tanks, maniac pirates
and other colourful cars are dangerous oppo-
sition. As the game progresses, the obstacles
gain in frequency and difficulty. First ifs just
nasty oil patches and water jum ps, but in later
rounds the track starts to resemble the grand
national with hurdles and tricky dead ends.
Jolly musical tunes, sensitive car control and
its theme give Burnin' Rubber irresistable
appeal and provides more than its money's
worth in entertainment value.
It's worth noting that Bumping Buggies from
Bubble Bus has exactly the same theme -
both companies got hold of the program and
altered it to suit themselves!

THE PIT
Your spacecraft has landed on an alien planet
which has an interior filled with rare jewels
and gems.
Luckily you are equipped with a powerful
drill and a laser gun and with these you have
to drill down to the depths of the cavern and
return to the spaceship carrying at least one
of the larger gems. To make your task even
more exciting, you have to return to your ship
before a surface tank destroys the mountain.
Some passages running through the rocks
already exist, but unfortunately they contain
patrolling robots which kill you on contact.
Otherwise you have to drill your own
passage through the rock, reach the jewels
and take care that boulders embedded in the
rock don't fall on you.
Once in the large Gem cavern, lethal
missiles drop from the roof and you have to
grab a stone and get out otherwise ifs
curtains. Once all the loot has been collected

your final obstacle is to negotiate a force field
and a nasty monster swimming in slime.
The Pit is based on the popular American

tion for the 64 with colourful bright graphics
and interesting sound effects. It is an
appealing exciting game.

PHAROAHS CURSE
Beneath the Sahara desert 43 centuries ago, a
wicked Pharoah constructed a death tomb
and cunningly hid 1 6 of his treasures within it.
Gold, art pieces, jewel encrusted scarabs -
everything was placed inside the various
passages and chambers and to guard them
he placed curses, traps, winged avengers, an
indestructible Pharoah and the dreaded
Mummie wanderers, inside.
You, the intrepid explorer have discovered
the entrance and now have the ominous task
MR MEPHISTO
The depths of hell are never pleasant a the
best of times, but you're at the very bottom
and somehow you have to climb the stairway
to heaven without falling into the flickering
flames or falling prey to ghouls, devils and
other unusual nasties.
Typical ly I never actual ly made it to heaven,
but the fi rst few stair levels were not easy. The
man you are controlling responds with ex-
treme sensitivity to the joystick so one false
move and he falls off the narrow walkways
into the flames. An epic poem, the Lament of
Hugo Twol (!) provides vital cl ues to the game,
so read it carefully. The basic aim is to climb
the stairs, open doors and avoid trouble.

The graphics in the game are excellent -
red, yellow and black devils creep around or
emerge from the floor very realistically. The
main nasty demon is a red cloaked figure
emitting jets of flame! The sounds are good
and skill and speed levels can be changed to
suit all abilities. It is fitted with Overdrive, a
fast loading mechanism.
Mr Mephisto is original, works very well and
is worth adding to your arcade collection.
SHEEP IN SPACE
Another game from Minter starring the
ungulate's. This time it's a metagalactic sheep
which flies around zapping Bonics (yes, white
dog biscuits) at everything in sight.
The planets are under attack by the energy-
draining hostiles which, if you're not quick
enough eventually build up an amazing
charge of energy on Planet Buster. As you flit
through the planet various aliens whizz by
and every so often you find yourself in mid
space between planets with even more ag-
gressive space persons.
Occasionally all the aliens disappear, but
don't despair, pressing the space bar activates
the time warp and you find some.
The sheep also has a stomach which starts
off bloated and gradually goes through
various stages of hunger - repleted, ad-
equate and peckish. Replenishing it is a feat in
itself as you try to land on the planet avoiding
the trees.
Yellow Llamas are introduced at every
opportunity although they don't do much
of collecting all items of treasure. Ifs not easy,
the traps set in the chamber floors are un-
predictable and everything that moves is
dangerous and needs to be shot.
As you travel through the chambers, finding
a treasure will give you an extra life and the
keys strewn around are needed to open the
cavern doors. Ropes can be used to pull your-
self out of sticky situations and every so often
a crown and arrow will appear. The former
grants an extra life and the arrow takes one
away.
There are four levels altogether, but each
level has to be completed before moving up
because completing a level is the only way to
discover the password.
Pharoahs Cursemakes excellent use of the
VIC 20's capabilities and both the graphics
and sound contribute to the game. It is
compulsive playing and all VIC 20 owners will
be thrilled to discover what their machine can
really do.

ENCOUNTER
Mysterious obelisks cover an alien planefs
surface and you, the commander of a probe
ship, swoop down to get a closer look. But
you find yourself locked in deadly combat
with cunning flying saucers and missiles.
The graphics create a superbly realistic
colourful 3D effect and the accompanying
sounds are excellent. You are looking out of
the front window of the ship and an instru-
ment panel combining a scanner screen and
three indicator warning lights warn you when
adverseries are approaching and if a shot has
been fired.
Both the missiles and saucers (recognised
by the sounds they make) are intelligent and
their pattern of movement gets more com-
plicated as the game progresses. The
graphics are so good that any shots fired by
either you or the enemies grow in size as they
approach you or recede into the distance and
in fact these obelisks can be used for
protection as any shots hitting them will
rebound.
There are eight levels altogether and some
very clever tactics will be needed to
complete them all. Each level has a certain
number of enemies that have to be des-
troyed and if you manage to hit them all, a
door appears and your ship enters a corridor
full of objects which if not avoided will
destroy you. Different landscapes and two
BIZY BEEZZZZ
Teddy gets lost on the way to the Bears Picnic
and is getting very hungry. Luckily there are
honey pots lying around on platforms
(pretend they are the woods!) and he has to
eat the contents of every single one.
The bees buzzing round these honey jars
are particularly possessive and any contact
with Teddy proves to be lethal, so make sure
you have a strategy before you start guiding
Teddy round the woods. The platforms are
connected by lifts and ladders and there are a
lot of gaps which need to be negotiated.
When making a jump, time it carefully
because the slightest miscalculation results in
instant death.
The control of Teddy is fairly sensitive and
the game is quite fun to play, but its best
feature is the excellent rendition of Teddy
Bears picnic.

ICE HUNTER
Ice Hunter is based on the exploits of Thorak,
the legendary Prince of Ice and this game
centres on his adventures in a multi level cave
(alternative phrase for several platforms!).
Each of the five cave levels contain blocks of
ice and Thorak's aim is to collect all the
blocks, float them down river to his igloo for
storage and return to collect more from the
five other caves.
To travel from level to level Thorak can slide
up and down icicle poles, but he must be
careful of thin ice patches. Once Thorak has
passed over one, the ice breaks and falling
through is fatal. However these holes do have
their uses because the blocks can be dropped
through.
Rampant arctic animals complicate matters
- sea lions, dragons, birds chase Thorak
round the cave and he can either drop blocks
onto their heads, avoid them or scoff a power
pill which paralyses them all. As the game
progresses these animals get more numerous
and aggressive and the levels start to move
around. To "do well, fast reflexes, tactical
movement and a little luck is needed.
Ice Hunter made its debut at the
Commodore show in June and was a great
success in our games competition.

TURTLE JUMP
Ekim, the giant ant, has undergone intensive
training in treasure recovery and is now in the
Caribbean Islands putting his lessons into
practise.
These islands are beyond the reach of
pirates and the only way Ekim can approach
them is to hitch a lift - anything solid will do —
logs and turtles for instance. The turtles have
slippery backs and move erratically, so Ekim
loses a lot of energy travelling.
Fruit lying around the magic islands will
replenish this energy. An energy bar across
the screen indicates how much power Ekim
has left.
Commodore Computing September 1984 9
rtT^eWe^ad*
Ekim's task is to jump into the treasure chest
whilst it's open, grab lots of loot and jump out
before it slams shut. Once enough treasure
has been recovered the pirates return and
collect it. The game is fraught with dangers
and Ekim must be especially wary of the croc-
odiles which periodically glide across the
screen. They cause all the turtles to dive and if
he happens to be on one's back, a precious
life is lost. In fact the magic islands keep
disappearing as well.
Turtle Jump is pleasant and enjoyable, but
not the sort of arcade game you write home
about.

STAR TROOPER
Not much to say about this one except that
you've all seen it before!
The Star Trooper clad in a smart white suit
carrying a jet pack on his back has the amaz-
ing task of destroying aliens as fast as they can
come. Every so often he will run out of fuel, so
an eye must be kept on the fuel meter at the
bottom of the screen.
In total there are 24 different types of aliens
and the aim is to defeat three of these enemy
wves, avoid the meteor clusters and pass on
to the next sector. Between each sector it is
necessary to dock and refuel. There are six
levels in all.
The graphics and sound were reasonable,
the controls of the spaceman were good but
the firing control wasn't really fast or
spectacular enough for a game in which
shooting is the only attraction. The program
also has a Pavloda fast loading mechanism.

LOCO
As you chug through the delightful country-
side, bomb-bearing aeroplanes, air ships and
explosive handcarts destroy the peaceful
calm. Fast reflexes plus other arcade skills will
be necessary to evade destruction.
Two angles of the game are featured on the
split screen — the side view of the locomotive
puffing along the track and a bird's-eye view
(radar scanner) of the six-track railway
showing its fuel dumps and any oncoming
airborne aircraft and handcarts.
You are in control of Loco and your two
defenses are lethal smoke puffs and missiles
from the front of the engine. There is a fuel
limit and the aim is to destroy everything
which could prove lethal and top up your fuel
from the dumps by switching tracks.
Each time you pass through a station, a
guard presents you with a flag and after five
flags, the next level is attained. There are two
skill levels - fast and slow and although the
game looks easy, it isn't!
The sound and graphic effects are excellent.
Loco is original and has enough lasting inter-
est to occupy a few free hours.

CAVELON
Clad in a red tunic decorated with a white
cross, the brave knight sets out on a quest.
Cuinivere has been locked up in a castle by
the Black Wizzard and you are in charge of
the rescue operation.
Six levels of increasing complexity and diffi-
culty challenge you and the aim on each one
is to gather all the pieces of the door,
signalling your elevation to the next floor.
Knights and archers follow you around with
arrows and balls which have to be dodged.
Points are awarded for picking up shields,
other assorted mediaeval equipment and
most important the Excaliburs which render
all your assailents harmless for a few seconds.
Save these for the final level when you en-
counter the wizard.
The graphics and sound are well done and
control of the knight is fairly sensitive.
Cavelon uses the fast loading Pavloda and is a
fairly gentle game which doesn't require
awesomely fast reflexes and split second

BATH TIME
Take two angels, one large elephant, one fish,
one white swan, a boy with a bucket and one
bath tub, mix them together, add a smattering
of music and background with fountains and
you've got yourself Bath Time, an original
game concept from PSS.
It is difficult to see what lasting arcade
attraction plugging and unplugging a bath
has, but it seems to work! You choose
whether you want to control the angel letting
water into the bath or the one unplugging it
and of course the speed and skill levels.
The aim is to keep the water level steady.
Too high and the swan swims away, too low
and the fish suffocates. To add masses of
excitement to the game, an elephant trots
along and d rinks half the tub at a suck or a boy
empties twenty gallons into the bath. There is
nothing violent in the game at all and it is, as
PSS suggest, a funny family game.

SWOOP
This was originally a BBC game but the 64
version is a great improvement. Based on the
arcade games Galaxians and Space Invaders,
Swoop is entertaining and great fun to play.
You control a ground based laser cannon
and are under attack from three species of
birdmen - blue hawks, green merlins and red
condors. They appear in formation and can
attack either row by row or by swooping
down individually.
The birdmen appear in successive waves
and the levels get progressively more diffi-
cult. The red condors are extremely nasty
and very fast while the blue hawks are a bit
slower. In addition to their airborne tactics,
these flying fiends drop eggs which, if not
annihiliated, lie on the ground for five
seconds and destroy anything which comes
into contact.
The graphics are particularly interesting. In
the background there are falling stars and if a
bird is hit, it explodes and falls a short distance
(rather like a firework in the sky). If your laser
base gets zapped, the pieces fly all over the
screen. The sounds are also good and accom-
pany the game well.
There are four skill levels and although
Swoop would get zero points for originality, a
lot of care has gone towards making it excit-
ing and fast.

GYRUSS
Three billion miles from Earth and two time
warps from Neptune, you suddenly get
homesick! It's a long dangerous trip home,
but you are equipped with five spaceships, as
many lives and and a very strong defensive
system.
Each warp is a stage in the trip back to Earth
and after Neptune, there are four other
planets - Uranus, Saturn, Jupiter, Mars with
three warps between each one to travel to
before Earth can be finally reached.
Space currents pull the ship into a circular
orbit and as it races round the centre point,
enemy Spaceships, Satellites and run away
meteors materialise suddenly on the screen
destroying you on contact or shooting out
space bombs.
Altogether there are four different enemy
formation and two types of satellite. If one of
the satellites is shot, your ship is awarded
double-fire power which effectively increases
its point scoring capacity.
It is also possible to score lots of points at
the Chance Stage. Four different enemy
plane formations appear and if you can hit all
forty ships, an extra ten thousand is added to
your score.
Bach's Tocatta and Fugue in D minor (music)
creates an exciting electric atmosphere and
the ship reacts sensitively and accurately to
joystick control. The game comes in cartridge
form and will keep you entertained for hours.

CHUCKIE EGG
Like many others, Chuckie Egg is a platform
game, but unlike some it does have a lot of
charm.
The action is based in a farmyard where
Hen House Harry must rush around collecting
the dozen eggs and corn strewn around on
each screen. His task is not easy because
rather aggressive pink, green and orange
ducklings wander about the screen. Their
movement is fixed, so are quite easy to avoid,
but on the nonth level his troubles multiply
because mother duck waddles onto the
scene and follows him everywhere.
There are six levels of difficulty ranging from
'those who prefer adventures' to 'suicidal
maniacs' and the speed at which Hen House
Harry races around the yard in the sixth level
is incredibly fast and very funny to watch.
Hen House Harry can jump across gaps in
platforms, up steps and down to lower levels.
The screens change and their complexity
increases, for example lifts appear on the
third level.
Chuckie Egg is quite entertaining and worth
playing.

Commodore Computing International provides. They tell us, we
are pleased to say, that there is absolutely no substitute
for 'CCI', the longest established and most authorative
Commodore magazine.
One way over this problem is to make a firm order for your
copy from the newsagent, making sure it is reserved for you.
Another, an increasingly popular solution is a subscription

International arrives at your own address and avoids any
possible disappointment.
The Special Offer
As a special concession, present subscribers have been offered

Joystick jamboree
Thinking about investing in a joystick? Sally Wood examines
the pros and cons of a number of joysticks,
acquiring a stiff wrist in the process
Most of the best fast action and arcade
games require a joystick and for 64 and
VIC 20 owners that can create some con-
fusion because there are literally dozens to
choose from.
Besides the usual switch type of joystick
with the base, fire button(s) and stick, there
are track balls, pressure sensitive joypads,
mercury and even a remote-controlled joy-
stick which is due to arrive in England very
soon.
Everyones idea of a perfect joystick differs.
Some like long, chunky sticks which lend
themselves to rough treatment and heavy
handedness while others have a light touch
and prefer a small sensitive stick requiring
only a gentle push.
We looked at a selection of 64 and VIC 20
compatible joysticks and played them with
two games which we thought would best test
their qualities - Exterminator from Bubble
Bus, a typical megazap game which requires
exact rapid fire and a lot of straightforward
evasive movement and to test the fine move-
ment qualities of the joysticks we used Killer
Watt from AHigata. In this game, minute
changes in speed and direction are essential
- even moving a millimetre too far can mean
instant death on the cavern walls.
As we tested the joysticks it became ob-
vious that each one had its own definite style.
Although they all have the same function, the
variety in size, sensitivity and response were
incredible. The prices also tended to vary
enormously.
The qualities we looked for included the
sticks sensitivity - whether it moved space-
ships or laser bases accurately, how quickly,
and whether you were left with severe wrist
strain after a particularly long game of
Exterminator. Other factors we thought
important were whether it was suitable for
both left and right handers, the number of fire
buttons, their positioning, the speed of firing
response, whether the joystick was equally
usable held on a desk top and in your hand
and its overall strength and ease of use. As we
have said there is more to a joystick than
meets the eye!
Our list is not intended to be a comprehen-
sive survey - but should give you some idea
of what is available. A
summarises our findings.
list at the end
ATARI
We start with the Atari joystick. One of the
best with a sturdy base and a short stick which
only needs a nudge to react immediately
(although we did have trouble moving in a
diagonal direction). It had an excellent rapid
firing capability, but left handers may find it
difficult to use as there is only one button on
the left hand side. We can testify for this joy-
stick's strength as we have been using it for
four years and it still works well. Excellent
value for money at £6.99.
COMMODORE
Commodore's own joystick was not one of
the best models we tested. It had a cheap
plastic appearance and the control and firing
capacity were distinctly mediocre. Small
enough for the hand, but too flimsy for desk
top use.
PRO ACE COMPETITION
The Pro Ace Competition joystick seemed to
be fairly solid with two fire buttons in strategic
positions. The stick was slightly stiff at first.
Because of its size it will probably suit people
who really like to feel the handle move. It
worked fairly well with both games.

STARFIGHTER
The Starfighter, which claims to be the ultim-
ate joystick — whatever that means!, has also
lasted us a year of aggressive games playing
and is still going strong! Both the fire button
and the stubby stick responded sensitively,
but again it may not suit a left hander. Equally
comfortable and useable on the desk or in
the hand, the Starfighter will satisfy both
aggressive game playing and a lighter, more
manipulative technique. Quite good value at
£12.95.
WICO RED BALL & STRAIGHT
STICK
Wico, like Kempston, have a number of sim-
ilar models in their range. The Red Ball
featured a globular red ball on top of a stick
whilst the Straight Stick has a much more
conservative handle. For £5 extra (£22.95) the
Straight Stick is available with a three way
grip. Both seem to be tough, comfortable to
use and worked on all aspects of the two
games.
Competition
Pro WOO
COMPETITION PRO 1000
The Competition Pro 1000, the 3000's little
sister, had exactly the same base but less fire
buttons. The narrow, much shorter stick was
sensitive, accurate and did not leave you
exhausted after a hard game. Despite the
rubber feet on the base it can only really be
operated in the hand and the fire button is big
enough to be used by both right and left
handers.
TRAK-BALL
From the Trak-Ball, one of the more unusual
controllers, we had a rather patchy response.
It worked perfectly with Exterminator which
only required straightforward movement,
but in Killer Watt and games where changes
in speed and direction are necessary it just
wouldn't work. Both sturdy and strong, it is
probably more suited to desktop rather than
hand held use.
DELTA 35C
The newest joystick, the Delta 35c was also
one of the best. It has a little stick, three small
fire buttons and resembles a television
remote control unit. The manufacturers
recommend that it be used while you are
comfortably sat in your favourite armchair
and in fact it's really very relaxing to use. Not
recommended for heavy handed people as
the stick only needs to be pushed around
gently to elicit accurate quick response. The
fire buttons were all conveniently placed,
worked well and it was a real pleasure to use.
Very good value at £10.
Competition
Pro 5000
COMPETITION PRO 5000
A rather funny looking joystick, the Competi-
tion Pro 5000 featured a short stick with a
bulbous control knob and two huge fire
buttons on the base. It fitted comfortably in
the hand and coped with both games. Its
rapid firing action had a particularly good
response.
Competition
Pro 3000
COMPETITION PRO 3000
The Competition Pro 3000 from Kempston
was one of the few joysticks with three fire
buttons. Two of them were placed on the
huge chunky handle with finger- grips, but
unfortunately they were not as responsive as
the button on the base! The stick started to
creak after a while, but it didn't make any dif-
ference to its relatively sensitive and quick
response. It would suit people who like a lot
of leverage from their joysticks, but we felt
exhausted after a few games of Killer Watt
because so much pushing and pulling was
involved. Pulling back the handle often
resulted in the fire button getting pressed
because the button is so awkwardly placed.
The base was too light for it to be used on a
desk top successfully.
JOY-SENSOR
The Joy-Sensor looks the most professional of
the lot, but unfortunately our high expecta-
tions were not met. Its rapid fire facility was
good, but the controlling anything with the
circular touch sensitive pad proved to be
hard work. We had to concentrate harder on
pressing the right area on the pad than on the
game.
QUICK SHOT 1
The Quick Shot 1 joystick distinguished itself
by sporting suckers on its feet and these
worked quite well. The handle was long and
nice to hold and it had a fire button on both
the handle and on the top left hand side.
Fairly good response with both games.
After looking at so many joysticks, you'd think
that we would know the secrets of the
perfect joystick, but unfortunately there is no
such thing. Every model had its own
particular feel and our advice to anyone
thinking of investing is to consider our
comments, so into every shop you can think
of and persuade the shop assistant to let you
play a selection of games. Really test the
joysticks well before breaking your piggy
bank. Happy Hunting!

"I'll swap four of my (apes
for your Acti vision!'
No way!"
You know the feeling. A couple of plays and
the best you can hope for from so much of the
software around, is swapping it for something better.
Well, the something better has arrived.
Activision.
One thing you can be sure of. Buy any
Activision software and you'll find you're walking slap,
bang into a totally new experience. One that lasts.

You have to colisct 12 eggs and corn to finish the

as you try to escape up the ladders. You can jump onto the
moving lifts but make sure you get off before you smash
your head against the roof.
The duckilngs are on a fixed path but if you're good

You're alone on a distant
planet, designed to train the great-
est warriors in the universe. For the first
time in millions o! years, YOU have
activated the combat grid. Can you survive?

It begins here!
O © O
INSTRUCTIONS
FOR SURVIVAL
In a galaxy, far, far away,
your starship is in orbit
around a strange new
world. You set off in a
Seeker-Probe to take a
closer look at the planet's
surface. Mysterious
obelisks litter the planet,
clouds hover menacingly
across the desolate plain,
when suddenly your
monitoring systems tell
you you're under attack.
The Encounter has begun!
An alien saucer flashes
onto your view screen.
Your ATTACK indicator
flashes and a bolt of raw
energy smashes into your
protective screen. Your
screen can only absorb
four hits of this intensity.
You must fight back!
"The graphics are
outstanding...it's 3D
impression is superb. The
Game itself is first class."
WHICH MICRO?
Brilliant!
"Encounter is a game that
will have Arcade game
lovers riveted to their
screens for hours on
end..." PERSONAL
SOFTWARE (USA).
"The graphics and sound
in this 3 dimensional
simulation are stunning"
